Audio cuts out when computer goes to sleep

Whenever my computer goes to sleep due to my leaving to go do something the game audio cuts out entirely and cannot be recovered. The rest of my computer audio is fine. I have to fully close the game and relaunch it for the problem to be fixed.

It's not a major issue, though was a bit frustrating on launch day when I had to rejoin the queues as a result of restarting the client.

In case it matters I play through the Steam version.
